Southern Illinois Realty Experts has been helping buyers, sellers, and investors since 2010.
OUR STORY
Founded in 2010 by Greg Holthaus with a simple mission: provide honest, expert real estate services to the communities he grew up in and loves.
What started as a one-person brokerage has grown into one of the region’s most trusted firms — with 23+ licensed brokers, three offices, and hundreds of families served.
We’re not a franchise. We’re a locally owned brokerage where every broker lives and works in the same communities we serve.
